diy pressure transducer

Heres my transducer i just got done building. i didnt put the capaciters in it like others do. also i put a connector on it for the sensor pigtail so i can use it for different sensors. 100 psi for fuel and 200 for small engines and so on. i hooked it up to the meter just for the pic btw. im thinking about making a test injector for my cummins but the rocker is ontop of the injector so it wouldnt be easy

You do realise the pressures in a diesel engine are way higher than 200psi ? For a compression test you need a 1000 PSI sensor and suitable pipe work fittments. As for the fuel rail pressure on a CRD diesel up to an immense 61,000 PSI the fuel rail already has a pressure sensor anyway you can hook up to or read via the diagnostic socket.

looks like the resolution turned out pretty darned good. im testing an old japanese mini truck and it looks like its saying the exhaust is plugged up.

yeah i realise that thats why i put the connector in line on the sensor pigrail so i can swap it out

im still not showing an intake stroke on here. i removed the muffler and its still the same. hmmm. im deciding if the problem is in the sensor transmitting data or the vehicle has a problem

If it is a cranking test not a running test it is what I would expect.

Try testing on a known good.
